Privacy and face matching
Do we need consent from guests?
The short answer
At an event that uses personal information or a matching selfie, it is important to give guests a clear explanation and point them to the privacy policy.
The exact legal requirement depends on the type of event, how the information is used, and the applicable law. So the right answer is not to rely on one short sentence on a website.
In practice, transparency helps both legally and on a human level: explain why you are asking for a selfie, what the guest gets, and where they can read more.
This question touches on privacy or data rights. The answer here is a general explanation; the binding documents are Matcha's Privacy Policy and Terms of Service.
